SAMUEL SMYTH, OF PITTSTON, PENNSYLVANIA.

STOVE-PIPE FASTENER.

i-ZPECIFICATION forming part of Letters Patent No. 302,674, dated July29,1884.

' Application filed December 29, 1883. (No model.)

To all whom it may concern.-

Be it known that I, SAMUEL SMYTH, of Pittston, in the State ofPennsylvania, have invented an Improvement in Stove-Pipe Fasteners, ofwhich the following is a specification.

Stove-pipes are usually inserted into a thimble of metal or earthenwarebuilt into the chimney. If the stovepipe is thrust in too far, itobstructs the chimney flue, and the draft through the stove-pipe is alsolessened. If the pipe is not secured to the thimble, it is liable tobecome disconnected, especially when eX- posed to vibration, such asusually occurs from walking upon the floor where the stove sets.

Efforts have been made to fasten the stove-pipe with a wire; but thesame is not well adapted to the differing thicknesses of brick-work, andcannot easily be disconnected for removing the stove-pipe.

My invention relates to a fastening-wire connected to the stove-pipe,and having two projections, one of which passes inside the inner end ofthe thimble, and the other passes outside the outer end of the thimble,the fastening being held so that it may receive nearly ahalf-revolution, in order that the inner projection may be turned backout of the way in entering or withdrawing the pipe, or turned down atthe end of the thimble within the chimney, so as to hold the pipe in itsplace.

In the drawings, Figure l is a section representing the pipe andfastening in place. Fig. 2 is an end View of the pipe and fastening.Fig. 3 shows theunder side of the pipe. Fig. i is the fasteningdetached, with a portion of the wire folded back upon itself; and Fig. 5shows the fastening device with only a coil at each end.

The pipe a is of any desired size, and the thimble I), of sheet metal,terracotta, or earth enware, is built into the chimney. c is the flue,and d is the brick-work of the same.

The wire fastening e is provided with a coiled or hooked end, f, that isadapted to be passed into the flue at the inner end of the stovepipethimble, and said fastening a has also the coil g, to rest against thechimney-surface. The wire 6 is folded back upon itself, as at h, so thatthe distance between the parts f and 9 may be varied by bending the wireat a different place or by coiling up or uncoiling the helix or coil 9.The body portion of the wire 6 is fastened to the pipe (0 preferably bybending into such pipe a groove or channel at t, laying such wire 6thereinto, then covering the same with a small plate, 3. This allows theparts to bepartially revolved, so that the coil f is out of the way whenthe stove-pipe is introduced into the thimble. Then the fastening ispartially turned the other way, the parts assume the position shown inFig. 1, so that the fastening secures the stove-pipe within the thimbleand prevents it moving in either direction; hence the stove-pipe cannotslip out of the thimble or pass too far into the fine, and to take thepipe down it is only necessary to turn the fastening around into theposition shown in Fig. 2, so that the coil end f is out of the way forremoving or inserting the pipe. I do not claim awire connected with thepipe and having a hook at the inner end capable of being turned to hookbehind the brickwork, as this has been used with a separate barconnected with the pipe and reaching across to the back of the flue.Neither do I claim a metallic strip independent of the pipe laid intothe fiue hole before the pipe is inserted, and afterward wired to suchpipe, as this wire has to be. separately fastened each time the pipe isremoved.

I claim as my invention-- The combination, with the stove-pipe, of awire having a hook at one end adapted to pass inside the brick-work, anda projection at the other end for the face of the chimney, and a plateor clip connecting the wire to the stovepipe, and in which such wire isfree to be par tially rotated, substantially as specified.

Signed by me this 21st day of December,A. D. 1883.
